Description

Technical Field

[0001] This utility model belongs to the field of fire protection facilities technology, specifically a fire hose connector that prevents detachment. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and an outer layer covered with woven linen. Advanced fire hoses are made of polymer materials such as polyurethane. Both ends of a fire hose have metal connectors, allowing connection to another hose to extend the distance or to a nozzle to increase the liquid spray pressure. During installation, fire hose couplings are used. These couplings are the connectors that connect hoses to other hoses, fire pumps, fire hydrants, and mobile fire monitors. They mainly include hose couplings, threaded joints, check valves, fixed threaded joints, pipe threaded joints, reducing joints, and non-standard joints.

[0003] Existing technology publication CN221121371U provides a fire hose anti-detachment interface, including an interface connecting pipe. A threaded pipe is fixedly connected to the outer surface of one end of the interface connecting pipe, and a fixed anti-detachment device is movably connected to the outer wall of the threaded pipe. A connection port is opened on the outer surface of one end of the interface connecting pipe, and a fixed clamp is movably connected to the outer wall of the interface connecting pipe. A movable leak-proof device is fixedly connected to the inner wall of the interface connecting pipe. When using this device, the upper connecting block and the lower connecting block in the fixed anti-detachment device cooperate with each other to clamp the fire hose using the threaded groove opened in its inner wall. Then, it is fixed by the screw fixing block and the nut connecting block. This can effectively prevent the fire hose from falling off and leaking water. The operation is simple and quick, allowing the water hose to be quickly connected in the event of a fire, enabling the water source to be quickly transported to the fire extinguishing, improving the efficiency of fire fighting operations and reducing the losses caused by fire.

[0004] However, in the use of existing anti-detachment fire hose connectors, after the fire hose is installed on the connector, it is fixed with clamps to form a longer water delivery line. However, this installation method mainly relies on clamps for fixation. When the water pressure is strong, the water pressure will force the fire hose to open. Since the fire hose connector does not have a self-locking function, the fire hose is prone to falling off.

[0005] To address this issue, those skilled in the art have proposed an anti-detachment fire hose connector to solve the problems raised in the background art. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an anti-detachment fire hose interface, which solves the problems in the prior art where fire hoses are mainly fixed by clamps, and when the water pressure is strong, the water pressure will open the fire hose. Since the fire hose interface does not have a self-locking function, the fire hose is easy to fall off.

[0007] An anti-detachment fire hose connector includes a connecting unit and a fixing unit. The connecting unit includes a connecting body, with connecting pipes fixedly connected to both ends of the connecting body. A locking sleeve is fixedly connected to the outside of the connecting pipe. A sliding groove is formed on the outside of the connecting pipe away from the locking sleeve. The sliding groove has an inclined structure, and an anti-detachment slider is movably connected to the inside of the sliding groove.

[0008] The fixing unit includes a fixing sleeve installed on the outer side of one end of the connecting pipe, a fixing plate fixedly connected to the outer side of the fixing sleeve, a screw hole on the top of the fixing plate, and a fixing ring fixedly connected to the inner side of the fixing sleeve.

[0009] Preferably, there are two connecting pipes, which are the same size and shape and are arranged symmetrically.

[0010] Preferably, there are six lock sleeves, with three lock sleeves arranged in groups of three, and each group of lock sleeves is arranged at equal intervals.

[0011] Preferably, both the connecting body and the connecting pipe are made of metal materials, and the connecting body and the connecting pipe are an integral structure.

[0012] Preferably, two fixing sleeves are provided, and the two fixing sleeves are combined to form a cylindrical structure.

[0013] Preferably, the top of the fixing plate is connected to a fixing screw via a threaded connection, and the inner diameter of the threaded connection is adapted to the diameter of the fixing screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through the design of a sliding groove and an anti-detachment slider, allows workers to secure the fire hose to the connecting pipe when using the anti-detachment fire hose interface. Workers then attach the fire hose to the connecting pipe, and finally attach the fixing sleeve to the already installed fire hose, encasing the anti-detachment slider. The fixing screws are then inserted into the screw holes for tightening. At this point, the fixing sleeve firmly clamps the connecting pipe and the fire hose. Simultaneously, the fixing ring and locking sleeve inside the fixing sleeve press against each other, forming the first layer of anti-detachment fixing. Furthermore, when the fire hose is forced open by water pressure and detaches from the connecting pipe, it pulls the anti-detachment slider. The anti-detachment slider then moves backward through the sliding groove. Because the sliding groove is an inclined structure, and the anti-detachment slider moves further backward through the groove, it exerts greater force to compress the fire hose from the inside out, forming the second layer of anti-detachment fixing. Therefore, this improves the fire hose's anti-detachment effect. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] In the description of this patent, it should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] Example 1: An anti-detachment fire hose interface includes a connecting unit 1 for connecting a fire hose, comprising a connecting body 101 for isolating, both ends of the connecting body 101 are fixedly connected to connecting pipes 102 for installing fire hoses, the outer side of the connecting pipes 102 is fixedly connected to a locking sleeve 103 for preventing the fire hose from detaching, and a groove 104 for sliding an anti-detachment slider 105 is provided on the outer side of the connecting pipes 102 away from the locking sleeve 103, the groove 104 is an inclined structure, and the inner side of the groove 104 is movably connected to an anti-detachment slider 105 for preventing the fire hose from detaching.

[0026] Furthermore, there are two connecting pipes 102, which are the same size and shape and are arranged symmetrically.

[0027] Furthermore, there are six lock sleeves 103, with three lock sleeves 103 arranged in each group, and the lock sleeves 103 in each group are arranged at equal intervals.

[0028] Furthermore, both the connecting body 101 and the connecting pipe 102 are made of metal materials, and the connecting body 101 and the connecting pipe 102 are an integral structure.

[0029] As can be seen from the above, when the fixing sleeve 201 and the connecting pipe 102 fix the fire hose, the fixing ring 205 and the locking sleeve 103 inside the fixing sleeve 201 will press against each other to form the first anti-detachment fixing effect. When the fire hose is stretched open by the water pressure and detaches from the connecting pipe 102, the fire hose will pull the anti-detachment slider 105. At this time, the anti-detachment slider 105 moves backward through the slide groove 104. Since the slide groove 104 is an inclined structure, and the further the anti-detachment slider 105 moves backward through the slide groove 104, the greater the force the anti-detachment slider 105 will exert on the fire hose from the inside out, thus forming the second anti-detachment fixing effect.

[0030] Example 2: This example is basically the same as the previous example, except that the fixing unit 2 for fixing the fire hose includes a fixing sleeve 201 for fixing the fire hose installed on the outside of one end of the connecting pipe 102. The fixing sleeve 201 is fixedly connected to a fixing plate 202 for butt joint installation and fixing. The top of the fixing plate 202 is provided with a screw hole 204 for installing fixing screws 203. The fixing sleeve 201 is fixedly connected to a fixing ring 205 for fixing the fire hose.

[0031] Furthermore, two fixing sleeves 201 are provided, and the two fixing sleeves 201 are combined to form a cylindrical structure.

[0032] Furthermore, the top of the fixing plate 202 is threaded with a fixing screw 203 for fixing the fixing plate 202 via a screw hole 204, and the inner diameter of the screw hole 204 is adapted to the diameter of the fixing screw 203.

[0033] As can be seen from the above, the fire hose is fitted onto the connecting pipe 102, and then the fixing sleeve 201 is fitted onto the connecting pipe 102 with the fire hose already installed, and wraps around the anti-detachment slider 105. Then, the fixing screws 203 are inserted into the screw holes 204 respectively for tightening. At this time, the fixing sleeve 201 will firmly clamp the connecting pipe 102 and the fire hose. At the same time, the fixing ring 205 and the locking sleeve 103 inside the fixing sleeve 201 will press the fire hose against each other, thus forming the first anti-detachment fixing effect.
